Dataset title: Periphyton Productivity from the Shark River Slough and Taylor Slough, Everglades National Park (FCE), from October 2001 to Present Dataset ID: LT_PP_Gaiser_004 Research type: Long-term Dataset Creator Name: Dr. Evelyn Gaiser Position: Primary Investigator Organization: Florida Coastal Everglades LTER Program Address: 11200 S.W. 8th Street Miami, Florida 33199 USA Phone: 305-348-6145 Fax: 305-348-4096 Email: gaisere@fiu.edu URL: http://serc.fiu.edu/periphyton/ Metadata Provider Organization: Florida Coastal Everglades LTER Program Address: Florida International University University Park OE 148 Miami, FL 33199 USA Phone: 305-348-6054 Email: fcelter@fiu.edu URL: http://fcelter.fiu.edu Dataset Abstract Periphyton productivity was measured annually at FCE LTER sites in Florida Bay and Shark Slough using light and dark BOD bottle incubations. Data are presented in terms of mass oxygen and/or carbon produced/consumed per gram of periphyton and per m2 of marsh. This is part of continuous data collection to test the hypothesis that phosphorus and nitrogen limit productivity at the upstream and downstream ends, respectively, of the FCE transects. Conclusions await longer-term data collection.

O2 was measured before and after 4 hours of incubation at ambient light. Production in BOD bottles is measured annually. Method Step Description A known volume of periphyton was collected from substrates (stems of emergent macrophytes, metaphyton, periphytometer slides, and/or benthos) and placed in light and dark BOD bottles. O2 was measured before and after 4 hours of incubation at ambient light. Light at the incubation depth was measured with a LiCor for the duration of incubations. Control bottles contained filtered in situ water. All bottles were brought back to the lab on ice and processed to calculate the mass of incubated mat. Citation Welschmeyer, N A 1994.

Light and dark control start and end O2 subtracted from light and dark treatments. Gross = dark respiration + light production. Each set calibrated per mol photon average light. Relative per gram productivity = mg O2 per gram ash-free dry mass per hour; Total per gram productivity = mg C per square meter per day (C= O2*1.2*0.375); Areal values calculated using biomass measures of periphyton for each incubated substrate type. Substrate type (P=periphytometer; M=mat; E=Epiphyton) Information Management Notes Information Manager (December 19, 2011): 1) The file LT_PP_Gaiser_004 should only contain the three values reported in the new file. This is because we realized that the other values carry assumptions that we feel less comfortable about now that we understand the data better. This new files should also replace the old file, ST_PP_Gaiser_002 & all previous versions. 2) Changed date format to DD-MMM-YY and coded missing values with -9999 (including changing NES and NS to -9999), 3) Corrected site names to reflect TS/Ph instead of TSPH and 4) Added new column names: Net_Carbon_Production and Net_Respirtation. (May 6, 2013): This is a long-term primary production dataset and subsequent data wil be appended. This dataset replaces all previous versions of LT_PP_Gaiser_004 original. The FCE program is discontinuing its practice of versioning data as of March 2013.
